Amazon AWS Certified Developer - Associate Sample Questions (Q325-Q330):

NEW QUESTION # 325
A developer is working on an ecommerce website The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available How can the developer update the application to meet these requirements with MINIMUM changes?

  • A. Rewrite the application to be cloud native and to run on AWS Lambda, where the logs can be reviewed in Amazon CloudWatch
  • B. Scale down the application to one larger EC2 instance where only one instance is recording logs
  • C. Install the unified Amazon CloudWatch agent on the EC2 instances Configure the agent to push the application logs to CloudWatch
  • D. Set up centralized logging by using Amazon OpenSearch Service, Logstash, and OpenSearch Dashboards

Answer: C

Explanation:
Explanation
The unified Amazon CloudWatch agent can collect both system metrics and log files from Amazon EC2 instances and on-premises servers. By installing and configuring the agent on the EC2 instances, the developer can easily access and analyze the application logs in CloudWatch without logging in to each server individually. This option requires minimum changes to the existing application and does not affect its availability or scalability. References
* Using the CloudWatch Agent
* Collecting Metrics and Logs from Amazon EC2 Instances and On-Premises Servers with the CloudWatch Agent


NEW QUESTION # 326
A company has a web application that runs on Amazon EC2 instances with a custom Amazon Machine Image (AMI). The company uses AWS CloudFormation to provision the application. The application runs in the us-east-1 Region, and the company needs to deploy the application to the us-west-1 Region.
An attempt to create the AWS CloudFormation stack in us-west-1 fails. An error message states that the AMI ID does not exist. A developer must resolve this error with a solution that uses the least amount of operational overhead.
Which solution meets these requirements?

  • A. Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI.
    Relaunch the stack for both Regions.
  • B. Build the custom AMI in us-west-1. Create a new AWS CloudFormation template to launch the stack in us-west-1 with the new AMI ID.
  • C. Manually deploy the application outside AWS CloudFormation in us-west-1.
  • D. Copy the custom AMI from us-east-1 to us-west-1. Update the AWS CloudFormation template for us-west-1 to refer to AMI ID for the copied AMI. Relaunch the stack.

Answer: D

Explanation:
This will allow the company to deploy the application to the us-west-1 Region using the same custom AMI that is used in the us-east-1 Region.


NEW QUESTION # 327
A developer maintains an Amazon API Gateway REST API. Customers use the API through a frontend UI and Amazon Cognito authentication.
The developer has a new version of the API that contains new endpoints and backward-incompatible interface changes. The developer needs to provide beta access to other developers on the team without affecting customers.
Which solution will meet these requirements with the LEAST operational overhead?

  • A. Define a development stage on the API Gateway API. Instruct the other developers to point the endpoints to the development stage.
  • B. Define a new API Gateway API that points to the new API application code. Instruct the other developers to point the endpoints to the new API.
  • C. Implement a query parameter in the API application code that determines which code version to call.
  • D. Specify new API Gateway endpoints for the API endpoints that the developer wants to add.

Answer: A

What is the MOST cost-effective way to solve the deployment issue?

  • A. Change the Auto Scaling group to six desired instances.
  • B. Change the deployment policy to rolling. Specify a batch size of 2.
  • C. Change the deployment policy to rolling with additional batch. Specify a batch size of 1.
  • D. Change the deployment policy to traffic splitting. Specify an evaluation time of 1 hour.

Answer: C

Explanation:

NEW QUESTION # 329
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node is application. To minimize these bugs, the developer wants to impendent automated testing of Lambda functions in an environment that Closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (Ct/CO) pipeline before the AWS Cloud Development Kit (AWS COK) deployment.
Which solution will meet these requirements?

  • A. Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda Documentation Invoke the handler function by using a unit testing framework. Check the response Document how to run the unit testing framework for the other developers on the team. Update the OCD pipeline to run the unit testing framework.
  • B. Create sample events based on the Lambda documentation. Create a Docker container from the Node is base image to invoke the Lambda functions. Check the response Document how to run the Docker container for the more developers on the team update the CI/CD pipeline to run the Docker container.
  • C. Install the AWS Serverless Application Model (AWS SAW) CLI tool Use the Sam local generate-event command to generate sample events for me automated tests. Create automated test scripts that use the Sam local invoke command to invoke the Lambda functions. Check the response Document the test scripts tor the other developers on the team Update the CI/CD pipeline to run the test scripts.
  • D. Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response Document the test scripts for the other developers on the team Update the CI/CD pipeline to run the test scripts.

Answer: C

Explanation:
Explanation
This solution will meet the requirements by using AWS SAM CLI tool, which is a command line tool that lets developers locally build, test, debug, and deploy serverless applications defined by AWS SAM templates. The developer can use sam local generate-event command to generate sample events for different event sources such as API Gateway or S3. The developer can create automated test scripts that use sam local invoke command to invoke Lambda functions locally in an environment that closely simulates Lambda environment. The developer can check the response from Lambda functions and document how to run the test scripts for other developers on the team. The developer can also update CI/CD pipeline to run these test scripts before deploying with AWS CDK. Option A is not optimal because it will use cdk local invoke command, which does not exist in AWS CDK CLI tool. Option B is not optimal because it will use a unit testing framework that reproduces Lambda execution environment, which may not be accurate or consistent with Lambda environment. Option D is not optimal because it will create a Docker container from Node.js base image to invoke Lambda functions, which may introduce additional overhead and complexity for creating and running Docker containers.
